The problem may be related to the fact that, as @Andrew has pointed out in his comment to your question, datetime values in your table contain milliseconds also, while you are passing the value that doesn’t contain milliseconds.

If that is so, you could change the WHERE clause of you DELETE statement like this:

WHERE PaymentDate >= @PaymentDate
  AND PaymentDate < DATEADD(second, 1, @PaymentDate)

Note, though, that this may lead to deleting more than one row. For example, you have data as follows:

Name    PaymentDate             amount id
------- ----------------------- ------ ----
…       …                       …      …
hemanth 2011-06-15 15:40:18.550 100    1003
hemanth 2011-06-15 15:40:18.987 100    1003
hemanth 2011-06-15 15:40:42.363 100    1003
…       …                       …      …

If we ignore milliseconds, then there are two rows here with the same value of PaymentDate. Maybe, a situation like this is impossible with your application and so you needn’t worry about that. I just wanted to make sure that you were aware that, technically, it could be possible to delete more than one record when you are using an incomplete date/time value as a parameter.
